A flow communication unit (240, 540, 640, 740, 840, 940, 1040, 1140, 1240) for establishing flow communication from a multi-use drug delivery device adapted for extended use, to a flow conducting device, wherein the drug delivery device comprises a reservoir comprising multiple doses of a liquid drug formulation, wherein the reservoir is adapted to pressurize the liquid drug formulation, wherein the flow conducting device (230) is adapted for conducting the drug to the subcutaneous tissue of a subject, wherein the flow communication unit is adapted for being in an unconnected and a connected configuration, whereby the flow communication unit (240, 540, 640, 740, 840, 940, 1040, 1140, 1240) is adapted to enable the extended use of the multi-use drug delivery device.

A drug injection system includes a cartridge adapter and a drug injection device. The cartridge adapter includes: a main body case; an attachment portion provided on the main body case used for attachment to the drug injection device; an accommodating portion that accommodates therein a drug cartridge; a piston; a piston gear that allows the piston to slide therethrough; a stopper that stops movement of the piston gear; and a release lever that releases a locked state of the piston gear. The drug injection device includes: a casing that accommodates therein a portion of the cartridge adapter; an engagement portion that engages with the cartridge adapter; a drive gear to which the piston gear of the cartridge adapter is connected; a motor connected to the drive gear; and a release bar that drives the release lever of the cartridge adapter.

Syringe tip caps are described herein. Such syringe tip caps may include a cup, a cap, a locking feature, a peelable seal and an absorbent material. The cap having locking features and a chamber appropriately sized to adapt to and interlock with an annular wall of the cup.

A sub-assembly for a medicament delivery device, the sub-assembly having a housing extending along a longitudinal axis from a proximal end to a distal end; a cap releasably attached to the proximal end of the housing; wherein one of the cap and the housing has a user-visible surface extending in a circumferential direction relative to the axis, the surface having a cut-out; wherein the other one of the cap and the housing has a protrusion in the cut-out; and wherein the cut-out defines a user-visible labyrinth which the protrusion must follow during use in order for the cap to be detached from the housing.

An assembly for an injection or infusion device includes i) a cartridge being closed by a septum and the surface of the septum being sterile and covered by a first continuous flexible strip, and ii) a fluid path unit comprising a cartridge holder and a fluid path compartment comprising a needle in an interior, the needle is configured to penetrate the septum of the cartridge through a passage in the fluid path compartment. The passage is closed by a second continuous flexible strip keeping the interior of the fluid path compartment in a sterile condition. The cartridge is inserted into the cartridge holder aligning the septum with the passage and sandwiching both strips between the septum and the fluid path compartment. Both strips may be simultaneously removable from the cartridge and fluid path compartment thereby, establishing a sterile connection between the septum and the interior of the fluid path compartment.

An injection device configured for attachment to the skin of a patient using an adhesive layer includes a release liner covering the adhesive layer thereby preventing skin attachment. The release liner comprises a sheet of material where a first surface contacts the adhesive layer, and an aperture defining a passage for a film connected to a first sterile barrier film located within the injection device. An end of the film is connected to a second surface of the sheet of material that is opposite to the first surface, and the release liner is covered by a strengthening sheet connected to the second surface and covering the aperture and the end of the film.

An injection device configured for attachment to the skin of a patient includes a housing and a skin adhesive layer attached to an external surface of the housing for attaching the injection device to the skin of a patient. A release liner covering the skin adhesive layer prevents the injection device from attaching to the skin. A film with one end connected to a surface inside of the housing forms a removable sterile barrier and the other end connected to an external surface of the release liner without contacting the skin adhesive layer. The housing, skin adhesive layer and release liner each include a notch defining a passage for the film so that the second end of the film can extend from the interior to the exterior of the housing.

The dual syringe with percutaneous cannula is a medical device for harvesting and transferring cells for autologous transplantation without the requirement of a surgical setting or ambulatory care. The dual syringe is a closed sterile system that allows for the harvesting syringe to harvest the cells/tissue from a first location of a patient which is then centrifuged to aggregate the cells. The aggregated cell pellet is transferred to a transfer syringe. The cell pellet is then reinjected by the transfer syringe into the patient at a second location for therapeutic purpose. The percutaneous cannula permits insertion of a cannula, with the assistance of a needle, without the need of a surgical incision or trocar.

A medicant injection device includes a compressible body, a tip, and an outer luer body. The compressible body has a proximal end, a distal end, and a plurality of bellows, and defines an inner cavity for holding a liquid medicant. The tip is positioned at the proximal end of the compressible body. The outer luer body includes internal threads, and is positioned over and engaged with the tip to form a first fitting therewith. The first fitting is configured to be connected with a second fitting. A medicant injection device includes a compressible body having first and second arms, a receptacle interconnected with the compressible body and defining an inner cavity, and a first fitting configured to engage a second fitting. The compressible body is configured to be compressed by forcing the distal end of the first and second arm toward each other.

Embodiments of the invention are directed to flush syringe assemblies comprising an integrated contamination-prevention device integrated with device connector flushing positioned so that the practitioner cannot forget to apply disinfectant. The flush syringe assemblies comprise a barrel with an elongate plunger rod disposed therein and a cap comprising a passageway. The plunger rod includes a stopper of which at least a portion can be embedded in the passageway of the cap to form a plug in the cap.
